The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave. Interval: The time between two specific ECG events. The intervals commonly measured on an ECG include the PR ...

Multifocal atrial tachycardia (MAT) requires three different P wave morphologies in one ECG with a QRS complex rate of > 100. Wandering atrial pacemaker (WAP) requires three different P wave ...

There is no associated P wave, although an independent normal P ... sinus depolarization would suppress it 2,3. Figure 2: An ECG obtained from a beagle dog 21 days later, showing six rhythm ...

A ventricular pacing stimulus occurs before each QRS complex (+). Prior to the ventricular paced complex there is a P wave; hence the mode of pacing is atrial-sensed ventricular-paced, or P-wave ...
